I don't think it is that, I have not knowingly changed anything. As an experiment I booted off a 10.10 live CD (and I did not see this problem at all back then) and was able to see the problem on shutting down the live CD session. In fact I have discovered another symptom which I think confirms that it must be hardware. If I leave it disconnected from the mains for a few hours and then plug it in it immediately enters the fault mode with the standby light flashing and the power button non-functional. I have to leave it plugged in for ten or fifteen minutes (presumably something is warming up) and then if I power cycle it is ok. I think it has to be hardware, I suppose the first thing to do is to try and find an old power supply and swap that over.
